IMPROVEMENT m FOLDING CHAIRS.

Specification forming part of Letters Patent No. 138,124, dated April22, 1873; application filed April 14, 1873.

To all whom it may concern:

Be it known that I, ASAHEL (J. BOYD, of Worcester, in the county ofWorcester and State of Massachusetts, have invented a new and ImprovedFolding Chair; and I do hereby declare the following to be a full,clear, and exact description of the same, reference being had to theaccompanying drawing forming part of this specification.

In the drawing, Figure l is a transverse section of a chair embodying myinvention, and Fig. 2 is a front elevation of the same.

0 D represent, respectively, the front legs and arms, formed in onepiece, A, out of wood or other suitablematerial, and reverselycurved,

as shown. B are the back legs, and E the back proper, of the chair. Thefront and back legs are connected together by means of links a, whichfit over around I) in front, and are connected in rear to the back legsby screws. The front legs are connected together by rounds b c, and theback legs by round d and seat-piece e. i F is a flexible seat, which isattached in the usual manner to the seat-pieces e f. The back E ispivoted at bottom to the back legs.

When the chair is unfolded in condition for use the back legs rest uponthe upper round of the front legs, whereby the weight of the occupant ofthe chair is distributed between the flexible seat and a rigid portionof the front legs; at the same time all liability to the flexible seatbeing unduly stretched by the spreading apart of the front and back legsis prevented by the links a.

This construction is simple, consists of few parts, is strong, and atthe same time admits of being folded into a small space, thus making achair that is both durable and capable of transportation at a smallexpense.

I claim as my invention- 1. The reversely-curved pieces A, forming thefront legs and arms 0 1), respectively, in combination with the back E,back legs B, and folding seat F, substantially as described.

2. The side pieces A, provided with a round, b, that subserves thedouble purpose of a connecting-pivot for one end of the links a and arest for the upper ends of the back legs, in combination with the linksa, seat F, back legs B, and back E, substantially as described.
